It is hard to believe that the news that we offer today passed almost unnoticed. I honestly do not know what to think: Is the tragedy suffered by Japan after the accident at the nuclear power Fukusima ends or begins right? The press release that we offer today reports that a third of the country’s soil is contaminated byCesium-137 . The 33 percent of the surface of Japan makes an amount more than alarming .Personally I fear produces. And as happened in the crash of Chernobyl , the authorities never told the truth in order to avoid alarm in the population , although the problem appears to be similar.
Finally it is possible that as happened after the Chernobyl accident mented, especially due to soil contamination by cesium-137 , The area around Chernobyl will never be fit for human beings . timely decontamination of the soil of a country feasible , using procedures generally “ex situ”. But carrying out such process becomes a huge extensions all in an almost impossible task . On this occasion would have to move millions of tons of contaminated soil decontamination plants.
One third of the soil of a country!. Everything depends on the level and type of radionuclides that eventually house the ground. However, as already denounced my sister,in this post, the falsehoods that usually pour the authorities concerned in order to reassure the public are impressive, with Chernobyl in glaring example of this. Food sovereignty of Japan could be seriously threatened, as also the health of millions. But where are the reliable data serve to clarify the magnitude of the problem?
Now we have spoken of radioactive contamination of soils in more than one occasion (see links in the text and end of post). bury the contaminated soil surface hides the reality of a problem rather than solve it . Finally, some of the contaminants will be retained in the deeper soil horizons or washed by stormwater, contaminated river sediments and / or aquifer , for today ignore the soils and marine ecosystems . We saw in this post and especially in that other , assoil types influence the retention of radionuclides , as well as economically unviable and often difficult work of decontamination of large areas of “soil”.
Wikipedia begins its chapter on the cesium-137 stating that:
Cesium-137 is soluble in water and highly toxic in minute amounts . Once released into theenvironment , is still present for many years because of its half life. May cause cancer 10, 20 or 30 years from the time of ingestion, inhalation or absorption, when a sufficient amount enters the body (…) Since 2005, Cs-137 is the main source of radiation in the area alienation around Chernobyl. Along with cesium-13 4, iodine-131 and strontium-90 , was one of the isotopes with greater health impact distributed by the explosion of the reactor .
Similarly, as noted in this connection : “ The highest levels of cesium-137 deposited on the surface soil layers where they are absorbed by plants, insects and fungi, entering the food chain . “ Moreover we also find in this website, when the extensions contaminated by cesium-137 are very large (…)
In the OU I, radiological contamination of soil in the former HWMF is above the remediation goals based on the risk for any future use. Due to the volume of contaminated soil, this area is the main subject of this feasibility study . The radionuclide predomienante usually cesium-137 (Cs-137), that the disintegration of the environment results in the emission of gamma rays.The predominance of radionuclides identified is cesium-137 (Cs-137), which, through decomposition, resulting in a gamma ray emission. This is a process which, from the ground, the pa deleteriously affects people and the environment espuestos . Levels of strontium-90 (Sr-90), emit beta rays, another concern, as they represent a potential future whether this element migrates to contaminating groundwater. Both radionuclides are of relatively short duration, with a half life of approximately 30 and 28 years respectively. Specific locations on a small scale alpha low levels of contamination by plutonium and americium in the soil surface have also been identified.
Therefore, one may suspect that, as happened in the crash of the central Russian authorities dimensionas Nippon hide the real problem. Finally, after all, the string of victims and affected will extend over decades . But Japan is not Soviet Russia, so that (….). But also talk about a crowded island , which already requires food supplies partially. For the same reason does not seem very viable migration of citizens from the affected area extended to other regions. Neither the health of the economy is currently very buoyant. Again sobremos citizens do not what to expect, which for those who suffer the problem is outrageous and immoral . Time to time!.Again, the most devastating effects of natural disaster may be yet to come. Hopefully not the case!. But the short history of nuclear accidents, full of lies official, leads to suspect the worst. Of course, because it is an industrial country “open” the eyes of the rest of the world, no doubt end up progresarse significantly in this type of decontamination. Triënte comfort! For those who pay the consequences. We expect and hope that sooner than sooner, the “rising sun” shine back to a people who have suffered enough, when we remember the tragedies of Hiroshima and Nagasaki .
The radiation from the reactors in Fukushima rotten Japanese territory has contaminated much of what had been calculated so far. Three new studies, two independents and one from the Nippon Government itself, warn that radioactive debris over dirty floors prefectures (provinces) of which were considered contaminated initially .
The Japanese government is working on an updated map of pollution that is carried out by helicopter, flying over such places as may contain traces of is ótopos radioactive cesium-137 or cesium-134, the most common accidents such as occurred after Fukushima . According to this last map, released by the Ministry of Science Nippon, would add another six to add 18 prefectures linens from a total of 47 .
A scientific study published in the journal PNAS official confirms this diagnosis. ” Cesium-137 contaminated land intensively over large areas of eastern and northeastern Japan, while the west was safeguards for the mountain formations , “said the joint work of the universities ofTokyo , Nagoya and California, performed with the support from the Norwegian Institute for Air Study .
According to his data, as well as the prefecture of Fukushima , the most affected are those ofMiyagi (with which bordered on the north) and Ibaraki (south). Along with these, are seriously affected by cesium-137 in the provinces of Iwate (north of Miyagi), Yamagata (northwest), Tochigi (south) and Chiba (south of Ibaraki). Data reported in this study show that 90% of the total land contamination by cesium-137 is produced by rain. The researchers, who aim to help focus the work of pollution, ensure that agriculture in the areas shown to be controlled .
The mountain formations prevented toxic materials were shared across the country, according to another study also published in the latest issue of PNAS. The mountains prevented the spread of radioactivity, but at the expense of their own health, as rainfall and orography made some solid Nipponese are now heavily polluted .
Furthermore, this weekend the rugged center first opened its doors to the press since the start of its decomposition on 11 March. There journalists attended the Minister of Environment and responsible for the nuclear crisis, Goshi Hosono, and the plant manager, Masao Yoshida, who took the presence of the press to apologize to the people and to make a startling confession: “Several times during the first week of the crisis, I thought I would die soon.”
Thanks to Yoshida, head of the heroes of Fukushima, the catastrophe was smaller because it ignored the order of their heads of Tepco to stop injecting seawater into the reactors . In Tokyo office did not want to spoil their investment in plant , and Yoshida knew the most important thing was to cool the reactors. Tepco about 40 shareholders sued the directors of the company for negligence, they claim more than 50,000 million euros.
